Why does the computer always appear the sound of an error box, but there is no error box?

First, first confirm that the hardware is fine. If the speaker is fine, the sound card is fine, and if you've tested it on other machines and it's really good, then you can read on. 2. Make sure all the cables are exactly right.

Then power on the speaker and turn on the volume switch. 3. Install the driver of the sound card correctly, if it is an onboard sound card, it is best to install the driver provided on the driver disk of the motherboard. (Actually, the computer doesn't make a sound, and many times it's because the sound card is not driven correctly.)

In general, after the sound card driver is installed, there will be a small speaker icon in the taskbar in the lower right corner. Fourth, if you are sure that the driver is installed correctly, then take a look at the volume settings in the computer. Here's how:

Double-click the speaker icon in the taskbar to see if the volume is turned off to the minimum or muted in the Volume Control and Waveform dialog box that pops up. If these two options are not available in the dialog box, click on the "Options" menu - select "Properties" - select "Volume Control" and "Waveform" in the "Show Volume Controls" and then set them correctly. Note:

Step 4 can only be set up after the driver for the sound card has been installed correctly. Special reminder: In fact, many times, the reason why the computer does not work properly is a small fault, soft failure, careful analysis, many times can easily solve the problem.

When that sound appears, is it checking for viruses?

It's okay if you do it too fast and too often

Hello! The computer appears: [The memory cannot be read and written], the reason is more complicated, please prescribe the right medicine!

1。Misconfigured! [Restart, after the computer brand is out, press F8, Safe Mode, Last Correct Configuration, Enter, Enter]!

2。System vulnerability! [360 Security Guard or Kingsoft Guard, or Keniu Free Antivirus, Repair: High Risk and Important, Other Ignores]!

3。Software Conflict! [Uninstall infrequently used software to keep the system stable, especially the same type of software, incompatible]!

4。The software version is outdated! [Use: (Drive Life), Update: Graphics Driver, Sound Driver! Other software, override installation]!

5。Virus Trojan! [Anti-virus software, full disk with hidden scan and custom scan, after completion, quarantine, completely deleted]!

6。Bad review plugin! [Keniu Free Antivirus, Jinshan Guard, or Talk Chain Hall 360 Security Guard, Clean Up Bad Comment Plug-ins]!

7。Suspicious startups! [360 system first aid kit, start first aid, file recovery area, completely delete files]!

8。System file corruption! [Kingsoft First Aid Kit], Extended Scan, Scan Now, Process Now, Restart Computer]!

10。Instruction Repair Method! Start menu, run, enter cmd, press enter, enter in the command prompt (copy is sufficient):

for %1 in (%windir%\system32\*.ocx) do regsvr32 /s %1

Paste, press enter, and when you're done scrolling, type again:

for %1 in (%windir%\system32\*.dll) do /s %1

Enter! Until screen scrolling stops, restart your computer!

It means that there is a program that has not been closed normally when shutting down, it may be a virus or something, and you had better eliminate them one by one.

There's a Trojan program.,Shutdown can't end this Trojan program.,So there will be an error prompt sound.。

Let's re-drive the sound card.

1. Award BIOS

1 Short: The system starts normally. Congratulations, there is nothing wrong with your machine.

2 Short: General error, please go to CMOSThe setup and reset the incorrect options.

1 long and 1 short: There is an error with the RAM or motherboard. Try to change the memory, if it still doesn't work, you have to change the motherboard.

1 long and 2 short: The display or graphics card is wrong.

1 long and 3 short: The keyboard controller is wrong. Check the motherboard.

1 Long 9 Short: Motherboard FlashRAM or EPROM error, BIOS corruption. Try a different block of flashram.

Constant ringing (with long, intermittent sounds): The memory module is not plugged in tightly or damaged. If it still doesn't work, you can only replace a memory module.

Ringing: The power supply and monitor are not properly connected to the graphics card. Check all the plugs.

Repeated, short ring: There is a problem with the power supply.

No sound and no display: There is a problem with the power supply.

2. AMI BIOS

1 Short: The memory refresh failed. Replace the memory module.

2 Short: The memory ECC verification error is incorrect. Setting the memory option for ECC check to disabled in CMOSSETUP will solve the problem, but the most fundamental solution is to replace a memory.

3. Short: The basic memory of the system (the first 64KB) failed to be checked. Change memory.

4 Short: The system clock is wrong.

5 Short: Processor (CPU) error.

6 Short: Keyboard controller error.

7 short: The real mode of the system is wrong and cannot be switched to protection mode.

8 Short: A memory error is displayed. If there is a problem with the display memory, try changing the graphics card.

9 Short: rombios test error.

1 long and 3 short: memory error. If the memory is damaged, it can be replaced.

1 long and 8 short: A test error is displayed. The monitor cable is not plugged in properly or the graphics card is not plugged in properly.

Try turning off your firewall and anti-virus software.

The control panel --- sound and audio equipment --- sound, and you can modify it according to your needs during the time you want to do so.

Start-Run-Enter'regedit'Open the registry and find [hkey current user control panel sound] and [hkey users.] respectivelydefault control panel sound], beep in and yes in extendedsounds.

Reboot into the system, the prompt tone has been canceled!

Hehe, nothing is mishandled. If you don't worry, you can use Optimizer to optimize the system.
